FAA (pdf link): A Boeing Model 787 airplane that has been powered continuously for 248 days can lose all AC electrical power due to the generator control units (GCUs) simultaneously going into failsafe mode. This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power. We are issuing this airworthiness directive to prevent loss of all AC electrical power, which could result in loss of control of the airplane. Guardian article: "In the latest of a long line of problems plaguing Boeing’s 787 Dreamliner, which saw the company’s fleet grounded over battery issues and concerns raised over possible hacking vulnerabilities, the new software bug was found in plane’s generator-control units."

A grim and forbidding land, devoid of human habitation, intolerant of the inexperienced, and merciless when it judges the foolhardy. On May 4, 1942, twelve men of the South African Air Force boarded three Bristol Blenheim Mark IVs and took off from the oasis of Kufra in the Libyan Desert. Only one made it back alive. [more inside]
Audio recordings show that airspace restrictions over Ferguson following the killing of Mike Brown, supposedly due to shots fired at helicopters, were actually to keep the media out. Meanwhile federal charges against Darren Wilson are looking increasingly unlikely.
“When we yelled ‘Brace!’ ” Brown said later, “I always described it as if you watched a wind come across a field of wheat and everything bends. That’s how it was. Everybody went down. It was like a field of wheat being blown over.” What a plane crash feels like: The inside story of an American aviation disaster — and miracle [more inside]

Previously on the blue. Raphael Pirker, a.k.a. "Trappy" was the first person ever to to fined by the FAA for the commercial operation of a drone. However, instead of paying up, Pirker decided to contest the ruling with a little pro bono legal help. Last Thursday evening, the judge issued his ruling. The judge dismissed the FAA's case, agreeing with the defense that since the FAA never created any legally binding rules for small drones to begin with, they cannot now apply rules that would be used for a pilot flying a full size manned aircraft to drone operators. For now, the ruling means that commercial operation of SUAS in the United States is, basically, legal. Within 24 hours of the ruling, the FAA appealed the case to entire board of the NTSB. SUAS experimenters who have been waiting in the wings are pleased with the ruling.
On September 20, 1956, just before the bars closed at 3 a.m., a single-engine plane landed on St. Nicholas Avenue near 191st Street in northern Manhattan. Behind the stick was 26-year-old Tommy Fiztpatrick, who pulled off the no-lights, no-radio "feat of aeronautics" while (allegedly) drunk to (allegedly) win a bar bet. Two years later, when a fellow patron called his story into question, Fitzpatrick did it again.

Raphael Pirker, a.k.a. Trappy, is a FPV pilot who came to be well known after the video from his New York flight went viral. While most of the media coverage of Trappy's NYC exploits was positive, the incident prompted a heated debate in the hobbyist community, and the authorities took a dim view of it. Shortly afterwards, Trappy was hired by a PR firm to do an aerial video shoot over the University of Virginia. The FAA, having banned commercial use of UAVs in 2007, took the unusual step of issuing a $10,000 fine for the unauthorized flight. Earlier this month Trappy's attorneys filed a response(pdf) to the FAA's action which questions whether the FAA holds jurisdiction over "model aircraft" in the first place. According to Wired Magazine, he court's decision could determine the future of model aviation and miniature UAVs in the US. Once again, the response from the hobbyist/entrepreneur community has been spirited. [more inside]
Scientists first discovered invisible gamma-ray flashes in Earth's atmosphere in 1991. This year, the radiation burst, known as dark lightning, was discovered to be linked to regular lightning flashes. Will you get zapped by dark lightning when flying through a thunder cloud? A single burst can give an airline passenger a lifetime's safe dose of ionizing radiation. But it is rare enough that, for now, the risk is thought to be minimal. The US Naval Research Laboratory is rigging balloons and aircraft to further study the radiation burst threat.

No other hangar in the world is commodious enough to accomodate the giant. With longer wings than a Boeing 747 (70m) and ¾ of the length of an Airbus A380, but with a maximum take-off weight of only 130 tons (less than a Boeing 767), the Bristol Brabazon was only built to hold 100 passengers. The hangar that was made for it is under threat of being demolished and replaced with housing after the closure of Filton Airport, Bristol. Luckily, the red-trousered Mayor of Bristol has promised to intervene. [more inside]

Once more into the breach! Shades of Neal Stephenson: a squadron of RAF Spifires has been unearthed in Burma and is on its way back to Old Blighty. One hopes they can be properly restored so the populace can witness the aircraft that saved England's bacon. At the very least, perhaps they'll appear in a Dr Who episode.

The Cold War resulted in a rather large number of interesting military research programs. One of these with which I'm familiar is the Aircraft Nuclear Propulsion program, which ran from 1946 to 1961. The basic idea? Modify a bomber (such as a B-36 bomber), creating an aircraft that could theoretically remain aloft for weeks at a time without refueling, much like ballistic submarines? The challenge? Shielding. Shielding the reactor alone would make the aircraft prohibitively heavy, so the idea was to primarily shield the crew compartment instead of the reactor. However, to study the concept, and evaluate various lightweight shielding concepts, two very novel and unique nuclear reactors were built at Oak Ridge National Laboratory: the Bulk Shielding Reactor, a novel "swimming pool reactor", and the Tower Shielding Reactor, an unshielded reactor that was hung 200' in the air dangling between 310' steel towers. While the program successfully demonstrated several of the concepts (including a nuclear-powered gas turbine engine running in Idaho, and a modified B-36 that carried a nuclear reactor but wasn't propelled by it (mentioned above), the program was canceled in 1961 due to feasibility and budget concerns.

Austrian research company IAT21 has presented a new type of aircraft at the Paris Air Show which has the potential to become aviation's first disruptive technology since the jet engine. ... The key to the D-Dalus' extreme maneuverability is the facility to alter the angle of the blades (using servos) to vector the forces, meaning that the thrust can be delivered in your choice of 360 degrees around any of the three axes. Hence D-Dalus can launch vertically, hover perfectly still and move in any direction, and that's just the start of the story.

A Zimbabwean cargo aircraft crashed earlier today at Shanghai-Pudong airport, killing three and seriously injuring four. It is not yet known why the aircraft, an ex Varig MD-11F (pic) operated by an airline called Avient, failed to become airborne, but the airline itself has received quite some attention recently. Headquartered in Salisbury, Wiltshire, United Kingdom, they almost went bankrupt, leaving behind massive debts in France, only to almost out of nowhere get this MD-11F, which crashed within a week of being acquired.

What does an aircraft company do when military contracts dry up? Fairey’s answer was to reinvent the helicopter and revolutionize the short-haul airline industry. After 15 years of effort, its unique project, the Rotodyne, came within an inch of achieving that goal. The Fairey Rotodyne, which first took to the air more than 50 years ago, was billed as the world's first vertical take-off commercial passenger aircraft. Fairey talked up expressions of interest from BEA in the UK, New York Airways and the US Army, but the crucial launch order never came. British government policy to rationalize the industry saw the end of the Rotodyne and Fairey as an airframe maker in 1962.
January: Newly sworn-in President Obama says, "We need greater investment in... essential systems like the C-17 cargo... aircraft, which provide the backbone of our ability to extend global power."

The ring wing or annular airfoil is an aircraft design which has been experimented with throughout the history of aviation with some interesting variations. It has served as the inspiration for several paper airplane designs, model airplanes of course, and a variety of children's toys. The capabilities imagined by the French coléoptère engineers of the 1950's and 1960's and the U.S. "flying tank" designers are available today at least in the form of unmanned vehicles (large PDF brochure, 6 minute video download, 1½ minute YT news clip). The technology has also been adapted to become the surfboard tunnel fin and there are underwater UAVs as well.
